I would like to ask some help in modeling again. Because I have earlier been using Google Sketchup, there are some very basic things that I have hard times to learn in Blender. This is mainly because the logic needs to be totally different when modeling with Blender.
How would you model this kind of arc in Blender, see picture? I would need to draw an arc that has end points in the corners of rectangular. Also, how would you do it in both Object mode (arc would be separate object) and edit mode?
Is there some addon available that could be useful?
